Hii.. had the same problem with my Great Dane..but..important don´t show the eardropper.. Then cuttle up on the couch..with some goodies.. best if you have a friend to distract him whit chatting, snacks ..and you slowly get your eardropper close to his ear..and tell him with sweet voice that nothing is going to happen..make a joke out of it..sound happy and laugh .. then I´m sure he soon will combine the eardrops with some some pleasure too.. Hope this could help you.. Best of luck..
